Hi rom, can you please post the .3dm model file with your object in it? That would make it possible to examine your geometry and give any model specific advice.

Just by looking at your screenshot alone, it appears you have dragged the slider towards the "Fewer polygons" side. You should only do that if you want a low poly result.

For an emphasis on better quality rendering you should drag the slider towards the "More polygons" side (towards the right) instead.

Also clear out "Avoid smaller than" , that also is for making lower polygon count.

It can sometimes also be good to put in a distance in "Divide larger than" like around 1/10 of your overall model width, to force more divisions.

It would help a lot if you could post the model file though.

What programs are you importing into where you're seeing the severe problems? Make sure you're not deleting vertex normals.
